Use of high resolution sonar for near-turbine fish observations (DIDSON) - We@Sea 2007-002 [PDF]

, 2010
In this study we investigate small scale distribution of pelagic fish within a windfarm by means of a high resolution sonar (DIDSON, Dual frequency IDentification SONar; Soundmetrics).

Unsteady hydrodynamics of full-scale tidal turbines [PDF]

, 2018
Due to the lack of full-scale measurements of the flow around tidal turbine blades, it is not clear if unsteadiness in the background flow can induce dynamic stall and the significance of this on the rotor’s performance. To investigate, we develop a model that couples dynamic stall, rotational augmentation and blade element momentum theory with real ...

Investigating Tidal Stream Turbine Array Performance Considering Effects of Number of Turbines, Array Layouts, and Yaw Angles

Journal of Marine Science and Engineering
The performance of a tidal stream turbine array can be affected by numerous factors. Investigating the connection between array power production and these factors will be helpful in improving the development of tidal stream energy.

Reliability prediction for tidal turbines

, 2021
Marine renewable energy has the potential to form a key part of the renewable electricity generation arsenal that is required for society to prevent catastrophic global warming. Device reliability is one of the great engineering hurdles facing the sector; operating cost effectively in the harsh open ocean is very challenging.

Misplaced fears? What the evidence reveals of the ecological effects of tidal power generation

Ecological Solutions and Evidence
Tidal energy is a dependable and clean power source that stands as a compelling alternative to fossil fuels. Despite this promise, tidal energy projects face barriers to practical implementation, and objections to proposed schemes often stem from ...

Numerical validation of the two-scale actuator disc theory for marine turbine arrays [PDF]

, 2015
The challenge in the hydrodynamic modelling of tidal and marine turbine farms is to take into account the interaction of flow events across a wide range of scales, such as the blade scale, turbine scale, array scale and regional scale.
